The act of a man cockblocking another man with just their presence on on the girls friendlist on Facebook.com.

Sorry, I shouldn't have friended your girlfriend on FB. I didn't know she was that fickle. I'm so sorry for the facebook cockblock so please forgive me. I just wanted to be her to be my FB friend and nothing else. Just because I talk to her doesn't mean anything, but thats just from my point of view. I'm sorry please don't feel insecure about her feelings for you. I didn't mean for that to happen. You can keep that ho. I can't help it.
